Description

Device and method for recommending contact information

Technical Field

The present disclosure relates to a method and apparatus for recommending contact information. More particularly, the present disclosure relates to a method and apparatus for recommending contact information using current context information of a user and a contact method.

Background

Unlike existing rule-based intelligence systems, Artificial Intelligence (AI) systems are a computer system that can achieve a level of human intelligence and enable machines to self-learn, self-determine, and become more intelligent. The more AI systems that are used, the higher the recognition (recognition) rate, and thus the more accurate understanding of the user's preferences can be achieved. Thus, existing rule-based intelligent systems are gradually being replaced by deep learning based AI systems.

The AI technique is composed of machine learning (deep learning) and basic techniques (element technologies) using machine learning.

Machine learning is an algorithmic technique for self-classifying/learning features of input data. The basic technique is a technique of simulating a cognitive function, a determination function, and the like of the human brain using a machine learning algorithm such as deep learning, and can be classified into a plurality of technical fields including, for example, language understanding, visual understanding, inference/prediction, knowledge representation, operation control, and the like.

Various fields to which the AI technique is applicable will be described below. Language understanding is a technique to recognize and apply/process human language/characters, including natural language processing, machine translation, dialog systems, question answering, speech recognition/synthesis, and the like. Visual compression is a process of identifying and processing objects in terms of human perspectives, including object recognition, object tracking, video searching, human recognition, scene understanding, knowledge of space, video enhancement, and the like. Inference/prediction is a technique for judging and logically inferring information and making predictions, including knowledge/probabilistic-based inference, optimization predictions, preference-based planning, recommendations, and so forth. Knowledge representation is a technique for automatically processing human experience information based on knowledge data, including knowledge building (data creation/classification), knowledge management (data utilization), and the like. The operation control is a technique for controlling the automatic driving of the vehicle and the activity of the robot, and includes motion control (navigation, collision, driving), steering control (behavior control), and the like.

With the development of communication technology, various functions of communicating with a person have been provided to a user terminal, and thus not only the number of contacts for making a voice call, sending a text message, and the like, but also the number of contacts provided for communication through a messenger, an e-mail, a Social Network Service (SNS), and the like have increased.

The above information is provided merely as background information to aid in understanding the present disclosure. No determination is made as to whether any of the above would be applicable to the prior art in connection with the present disclosure.

Disclosure of Invention

Technical problem

It is difficult to remember a large number of contacts for various types of communication channels. For the convenience of the user, each communication channel program provides a function of recommending contacts in various ways. However, in most existing methods of recommending contacts, contacts are simply recommended based only on the number of calls and the duration of each call. Therefore, there is an increasing need to subdivide and recommend contacts based on the user's context.

Solution scheme

The present invention provides an apparatus comprising a processor and a memory configured to store instructions executable by the processor. The processor is configured to execute instructions to extract context information from the displayed data based on an application being executed by the apparatus, identify an identifier from the context information, search for at least one recommended contact related to the identifier based on the identifier and a relationship graph, identify a priority of the at least one recommended contact, and control to display the at least one recommended contact according to the priority, wherein the relationship graph is obtained by inputting information about communications between a plurality of users to a first training model for determining associations between the plurality of users.

Advantageous effects

The present disclosure enables providing a method and apparatus for recommending contacts based on context information and a relationship with a user.

Fig. 1 is an overview diagram of a method of recommending contacts, performed by an apparatus, according to an embodiment of the present disclosure.

Referring to fig. 1, in one embodiment, the apparatus 10 may identify at least one identifier, such as a first identifier 101, a second identifier 102, and a third identifier 103, from context information of an application being executed in the apparatus 10.

In one embodiment, the identifier may be a text keyword or a facial feature point identified by facial recognition. The device 10 may identify at least one identifier and a group identifier that are related to each other.

In one embodiment, the apparatus 10 may extract words using a specific frequency or higher in the context information as identifiers by using a language processing algorithm. In this case, the identifier may be a keyword.

In one embodiment, the apparatus 10 may obtain the keywords by maintaining a mapping between two or more dictionaries such that a word or phrase of one dictionary maps to another word or phrase of another dictionary. In one embodiment, when there is an association between a word or phrase in one dictionary and a word or phrase in another dictionary, the apparatus 10 may obtain keywords that are interchangeable with each other by using the mapping. The association may represent a method associated with a pair of nodes corresponding to a pair of data. In various embodiments, associations may be represented by predicates (predicates) having a pair of data or nodes as subject and object, respectively. In one embodiment, the association between two or more dictionaries may include, but is not limited to, the same relationship or an inclusion relationship. For example, unless the context requires otherwise, the words "korea" and "KR" having the same relationship are interchangeable with one another. Unless the context requires otherwise, the words "sports" and "basketball" are interchangeable as inclusive. The dictionary may be a language dictionary, a search context dictionary, an AdWords dictionary, a user intent map, or a user defined dictionary. The language processing algorithm may be, for example, a neural language programming algorithm, a natural language processing algorithm, or the like, or may include various algorithms or combinations thereof for analyzing and processing human language. In one embodiment, the apparatus 10 may extract a face detected at a specific frequency or higher from the context information as an identifier by using a facial recognition algorithm. In this case, the identifier may be a facial feature point.

The apparatus 10 may detect feature points on a face region by using coordinate information corresponding to a face. For example, the coordinates of the positions of the eyes, nose, mouth, and ears of the face may be used to detect feature points on the face region. In one embodiment, the facial recognition algorithm may include an algorithm, for example, using a combination of a motion compensated fuzzy neural network (DCFNN) and feature plane Linear Determinant Analysis (LDA), and combinations of algorithms.

In one embodiment, the apparatus 10 may obtain context information for an application currently being executed. In one embodiment, the application may include a mail, a Social Network Service (SNS), a text, an album, a diary, news, and the like, but the type of the application is not limited thereto. In one embodiment, the context information may include photos, pictures, text, moving pictures, animations, etc. included in the application. Optionally, in one embodiment, the context information may include a current time, a runtime of the application, properties of the application, a type of the application, and the like.

In one embodiment, the apparatus 10 may obtain the context information from the data displayed thereon by executing an application in the apparatus 10. In one embodiment, the apparatus 10 may obtain contextual information based on the text displayed thereon. For example, the text displayed on the apparatus 10 may include at least one of an email header, an email body, a sender, and a recommender (referrer) displayed thereon by executing an email application. In one embodiment, the apparatus 10 may obtain the context information by using different weights according to the fields including the text. For example, the apparatus 10 may obtain the context information by assigning the maximum weight to the text included in the title of the email and the minimum weight to the text included in the recommender. Alternatively, the apparatus 10 may obtain the context information by classifying the text into different categories according to the fields including the text. For example, the apparatus 10 may obtain the context information by classifying the text included in the header of the electronic mail into a "destination" category and classifying the text included in the sender into a "person" category.

Alternatively, the apparatus 10 may obtain the context information based on the image displayed thereon. For example, the image displayed on the apparatus 10 may include at least one of a moving image, a still image, and a representative image displayed for a certain time by executing a moving picture application. In one embodiment, the apparatus 10 may use different weights to obtain the context information according to the fields comprising the image. Alternatively, the apparatus 10 may obtain the context information by classifying the text into different categories according to the fields including the image. In one embodiment, the apparatus 10 may analyze the context information, extract at least one identifier, e.g., at least one keyword and at least one facial feature point, and identify a trend of the context information by using the extracted identifier. For example, when the first identifier 101 is "mother's face", the second identifier 102 is "family travel", and the third identifier 103 is "joy", the apparatus 10 may recognize that the trend of the currently performed context information is "pleasant family travel". In one embodiment, the apparatus 10 may process the plurality of identifiers into text representing a time series of operations based on the plurality of identifiers to determine a trend of the context information. For example, the apparatus 10 may generate text such as "the user has searched for famous places of travel in canada", "the user has searched for restaurant information in canada", and "the user goes to and John and Tom play basketball", based on the plurality of identifiers, and identify trends in the context information based on the generated text.

In one embodiment, the apparatus 10 may search for a recommended contact associated with the identifier. The apparatus 10 may search for a plurality of recommended contacts associated with a plurality of identifiers. The apparatus 10 may search for a recommended contact associated with the at least one identifier using a training model based on deep neural network techniques.

The apparatus 10 may search for a recommended contact associated with one or a combination of identifiers. For example, when the first identifier 101 is "mother's face", the second identifier 102 is "family travel", and the third identifier 103 is "joy", the apparatus 10 may search for family contacts as recommended contacts.

In one embodiment, the apparatus 10 may identify a priority for searching at least one recommended contact. In one embodiment, the apparatus 10 may identify a priority of the recommended contact in consideration of a contact frequency, a contact time, a contact method, a contact period (period), and the like with the recommended contact.

In one embodiment, the apparatus 10 may display the recommended contacts on a portion of the display. In one embodiment, the device 10 may display the recommended contacts in a pop-up window, on a separate window, or in the form of a message.

In one embodiment, the apparatus 10 may display the recommended contacts in a pop-up window 104 at the lower end of the screen. In one embodiment, the pop-up window 104 may include Identification (ID) information 106 of the recommended contact, e.g., the name of the stored recommended contact. In one embodiment, the pop-up window 104 may include an icon 107 for recommending a contact method for the contact. In one embodiment, the detailed information 105 of the recommended contacts may be displayed in a pop-up window 104. The detailed information 105 of the recommended contact may include a phone number when the contact method is a phone call, and may include ID information when the contact method is an SNS.

Fig. 2 is a flow chart of a method of operating a device according to an embodiment of the present disclosure.

Referring to fig. 2, in operation 201, in one embodiment, the apparatus 10 may identify an identifier from context information of an executing application. In one embodiment, the apparatus 10 may identify the at least one identifier in the context information by using a language processing algorithm or a facial recognition algorithm. In one embodiment, the identifier may be identified using words, synonyms, similar words, etc. that are detected at a certain frequency or higher.

In operation 202, in one embodiment, the apparatus 10 may search for at least one contact associated with the identifier. In one embodiment, the apparatus 10 may obtain an Artificial Intelligence (AI) training model based on a learning (graphical learning) result of a relationship between an identifier and a plurality of pieces of contact information using information on a history of the identifier used for a certain period of time.

For example, the apparatus 10 may process the plurality of identifiers into text representing a time series of operations. For example, the apparatus 10 may create text such as "the user has searched for famous places of travel in canada", "the user has searched for restaurant information in canada", and "the user goes and John and Tom play basketball", based on the plurality of identifiers.

In one embodiment, the apparatus 10 may learn relationships between a user and other users (e.g., contact owners) or between another user and other users by using information about communications between the user and the other users. The information about the communication may include frequency of contact, time of contact, location of contact, affinity of contact, common interests, affinity, etc. between the plurality of users. The apparatus 10 may be trained by inputting the above-described communication information into a first training model for determining an association between a plurality of users, and may generate a relationship graph based on the training result.

For example, the apparatus 10 may generate a relationship graph that is trained to match other users associated with travel or foreign countries that contact the user very frequently with the user in a "travel" relationship. Alternatively, the apparatus 10 may generate a relationship graph that is trained to match other users who contact the user very frequently who are performing the same workout to the user or users in the "workout" relationship. The relationship graph will be described in more detail below with reference to fig. 4.

In one embodiment, the apparatus 10 may identify an association between the identifier and the relationship graph by using an AI training model and search for a recommended contact based on the identified association. In one embodiment, the AI training model may be learned to recognize associations between identifiers and relationship graphs using text processed using the time series operations described above.

For example, when extracting "canada" as the identifier, the apparatus 10 may identify contacts of other users that match the user in the "travel" relationship in the relationship graph as recommended contacts by using an AI training model trained based on information about the history of use of "canada" with "travel".

When "John's face" is extracted as the identifier, the apparatus 10 may identify, as the recommended contact, a contact of Tom that matches John in the friendship relationship in the relationship graph by using an AI training model trained based on information about history of use of "John's face" with "Tom's face". However, the above-described case is merely an example, and the AI training model trained based on the historical information and the relationship graph according to the present disclosure are not limited thereto.

In one embodiment, the apparatus 10 may search for at least one recommended contact by using the obtained AI training model.

In operation 203, in one embodiment, the apparatus 10 may identify a priority of the searched at least one recommended contact. In one embodiment, the apparatus 10 may identify the priority of the at least one recommended contact based on historical information such as the number of contacts with the at least one recommended contact, a contact method, a contact period, and a relationship with an identifier and current information such as a current time, a current location, and information about an application currently being used.

In operation 204, in one embodiment, the apparatus 10 displays at least one recommended contact according to the priority of the recommended contact. In one embodiment, the apparatus 10 may display a plurality of recommended contacts simultaneously or sequentially. In one embodiment, the apparatus 10 may simultaneously display at least one connection method linked to at least one recommended contact or may display one of the at least one connection methods at a time.

Fig. 3 is a schematic diagram illustrating a method of recommending a contact by using an identifier, the method being performed by an apparatus, according to an embodiment of the present disclosure.

Referring to fig. 3, in one embodiment, the apparatus 10 may identify a first identifier 101, a second identifier 102, and a third identifier 103 in the context information.

In one embodiment, the apparatus 10 may search for at least one recommended contact by using an AI training model obtained based on a result of learning the relationship between the identifier and the pieces of contact information (graph learning).

In one embodiment, the device 10 may assign weights to the contact information used based on the application, duration, time, frequency, and location of the use identifier. Further, the apparatus 10 may identify at least one recommended contact based on the assigned weight.

In one embodiment, the apparatus 10 may collect a history of usage of at least one personal contact function (such as calls, text messages, messenger, email, SNS, etc.). In one embodiment, the usage history may include the date and time when each function was used to make the contact. In addition, the usage history may include a call time when the call function is provided, and may include contact details for using the remaining function when the call function is not provided.

In one embodiment, the apparatus 10 analyzes the collected usage history of each function according to at least one criterion of duration, time and frequency to assign a weight to the used contact. For example, a contact that was frequently used in the last few days may be selected by assigning a weight of 2.0 to a contact that was used within the last two days, or a contact that was frequently used in a time zone in which the user was primarily communicating with an intimate contact may be selected by assigning a weight of 1.5 to a contact that was used from 6 pm to 12 pm.

In one embodiment, the apparatus 10 may assign a weight to a contact that has exchanged words or emoticons expressing a predetermined emotion in the usage history of a personal contact function other than the call function. For example, a contact with a high affinity may be selected by assigning a weight of 2.0 to an email contact history that includes the word "love" or its emoticon. Conversely, a contact related to a loan advertisement or the like may be selected to have a lower priority by assigning a weight of 0.1 to the email contact history including the word "loan".

In one embodiment, the apparatus 10 may select at least one contact as the recommended contact by identifying a priority of the contacts for each function.

In one embodiment, when one of the recommended contacts corresponding to each function displayed on the screen is selected, the apparatus 10 may activate a contact method linked to the selected contact. In addition, the apparatus 10 may assign a weight to the recommended contact selected by the user, so that the frequently selected contact may be recommended more frequently. In one embodiment, the apparatus 10 may assign a weight to contacts that have been selected more than or equal to a predetermined number of times. Thus, the apparatus 10 can achieve an effect of activating the use of the recommended contact more.

In one embodiment, the apparatus 10 may identify a recommended contact, including the recommender 302 and the contact method 303. In one embodiment, the recommender 302 may be identification information, such as a person or company highly related to at least one of the first identifier 101, the second identifier 102, and the third identifier 103. In one embodiment, the apparatus 10 may identify an identification name for identifying a recommended contact received from an internal repository, cloud, or server and associated with a plurality of identifiers. In one embodiment, the identification name may include a name stored in the device 10, a company name searched through a network, and identification information on the recommender 302 searched through an SNS.

In one embodiment, the apparatus 10 may search for at least one contact corresponding to the recommender 302. In one embodiment, the contacts corresponding to the recommender 302 may include an SNS address, an available phone number, a mail address, an SNS ID, and the like. In one embodiment, the apparatus 10 may identify the priority of the recommender 302 by reflecting information detected in association with at least one identifier. For example, a contact of the family member "mother" may be given priority when at least one identifier (e.g., the first identifier 101, the second identifier 102, and the third identifier 103) is associated with a family trip.

In one embodiment, the apparatus 10 may identify a priority corresponding to the contact method 303 of the recommender 302. In one embodiment, the apparatus 10 may identify the priority of the contact method 303 by reflecting information detected in association with at least one identifier. In one embodiment, the apparatus 10 may identify a priority of the contact method 303 corresponding to the recommender 302 based on weights assigned according to frequently used contact methods, most recently used contact methods, contact locations, and the like. For example, when a phone call is often used as one of the recommenders 302 and its priority 301 is "mother" for the number 1 of family trips, it may be determined that the phone call is the first level (rank) contact method 304 linked to mother. Similarly, the text message may be determined as a second level contact method 305, and the SNS may be determined as a third level contact method 306.

FIG. 4 is a schematic diagram illustrating a method of creating a relationship graph from affinity between contacts according to an embodiment of the disclosure.

In one embodiment, the apparatus 10 may learn relationships between the user and other users based on information related to communications between the user and other users. In one embodiment, the apparatus 10 may learn the relationship by using a frequency of contact with other users, a time of contact, a location of contact, an affinity of contact, a common interest, an affinity, etc., and may create a relationship graph based on a result of learning the relationship.

In one embodiment, the apparatus 10 may reflect untagged information such as information newly disclosed through SNS, mail, phone call, etc. to the initial graph based on tagged information such as names of other users, contacts, groups to which the other users belong, frequency of contact, etc. stored in advance.

Referring to fig. 4, the circle nodes represent people. The location and color of the nodes may be data fields indicating similarity, interest, intimacy, etc. between the nodes. In one embodiment, a node may include a plurality of patterns, each pattern occupying an area. The shape of the pattern may represent different data fields, and the area occupied by the pattern in the node may represent the relative ratio between the values of the data fields. In one embodiment, for example, in the first graph of FIG. 4, B1 and B2 have a common interest in a common data field, namely, "Canada". In the relational graph, R1 is interested in the data field, i.e., "travel".

In one embodiment, each line connecting nodes may represent a relationship between users corresponding to the nodes. The thickness (thickness) of each line connecting nodes may represent the strength of the relationship between the nodes. The strength of the relationship may include affinity, similarity, whether each node belongs to a common group, and the like. For example, in the first group of fig. 4, the strength of the relationship between B2 and G3 may be greater than the strength of the relationship between G3 and G2. In the graph of fig. 4, the thickness of each line connecting nodes may be a value indicating the strength of a relationship normalized based on data fields included in the respective nodes. However, the thickness of each line is merely an example, and in the graph of fig. 4, each line connecting nodes may be provided for one of the data fields. For example, B2 and G3 may be connected by a line having a first thickness based on the "travel" data field and may be connected by a line having a second thickness based on the "canadian" data field. Alternatively, each line connecting nodes may represent a field indicating an association as well as a value. For example, fields indicating associations represented by lines connecting B2 and G3 may include the same relationship sameAs, membership relationship type, containment relationship subbackof, and so on.

In one embodiment, the device 10 may create the initial graphic using information obtained based on predefined people and communication information. In the first graph of fig. 4, G1, G2, and G3 have not been learned.

With the first training, the device 10 may train G2 based on the content of the conversation, message, or mail between B1 and G2. Referring to the second graph of fig. 4, it is noted that the similarity of G2 related to canada increases due to the effect of B1. Meanwhile, G3 may be trained based on the relationship between B2 and R1. Since the strength of the relationship between G3 and B2 is greater than the strength of the relationship between G3 and R1, G3 can be trained by assigning higher weight to canada than to travel.

Referring to the third graph of fig. 4, through the second training, the apparatus 10 may learn a relationship graph based on information related to communication of B1, B2, G1, G2, G3, and R1. In one embodiment, G2 and G3 may be trained based on the strength of the connection and information related to communications in the device 10. In one embodiment, through the second training, the importance of canada and travel interests in G2 and G3 may be changed. Referring to the third graph of fig. 4, a similarity related to travel is created in the case of G2, and the importance of interest in canada becomes higher than that of travel in the case of G3. In addition, G1 is linked to B1 via G2, and thus the interest in canada increases in importance.

As described above, the relationship graph between B1, B2, G1, G2, G3, and R1 can be trained by repeated training using information collected from the apparatus 10 and information received from the outside. In one embodiment, when a user writes a message about "travel to canada" by using the device 10, G2 and G3 may be searched for as recommended contacts based on the extracted identifiers "canada" and "travel".

Fig. 5 is a schematic diagram illustrating a method of estimating recommended contacts from a mail of a user by using a user relationship graphic, which is performed by an apparatus, according to an embodiment of the present disclosure.

Referring to fig. 5, in one embodiment, the device 10 may provide a mail service to the user Tom. The device 10 may display mail received from traveling Sunny on day 11/1 of 2017. In one embodiment, the device 10 may identify the identifier by analyzing the content of the mail received from Sunny.

The data learner 1310 may learn a graph showing relationships between the user and other users based on information related to communications between the user and other users. The data learner 1310 may learn the type of data to be used, thereby increasing the accuracy of the relationship graph and whether to extend the relationship graph with the data. The data learner 1310 may obtain data to be used for learning and learn criteria for forming an appropriate relationship network by learning a relationship graph that applies the obtained data to a data recognition model (described below).

In one embodiment, when there are a plurality of pre-established data recognition models, the data learner 1310 may identify a data recognition model that is highly correlated with the input training data and the base training data as the data recognition model to be learned. In this case, the basic training data may be classified in advance according to the data type, and a data recognition model may be established in advance for each type of data. For example, the basic training data may be classified in advance by various criteria, such as a place where the training data is created, a time when the training data is created, a size of the training data, a kind of the training data, a creator of the training data, a type of an object included in the training data, and the like.

The data identifier 1320 may increase the accuracy of contact recommendations based on the relationship graph of the user, as the case may be. Based on the results of learning the relationship between the context identifier and the pieces of contact information by using the learned data recognition model, the data identifier 1320 may increase the accuracy of the contact recommendation. The data identifier 1320 may obtain data according to a predetermined standard by learning and use a data recognition model using the obtained data as an input value to improve the accuracy of the contact recommendation. The resulting value output of the data recognition model using the obtained data as input values may be used to update the data recognition model.

At least one of the data learner 1310 and the data identifier 1320 may be fabricated in the form of at least one hardware chip and installed in the apparatus.

For example, one of the data learner 1310 and the data identifier 1320 may be included in the apparatus, and the other may be included in the server. The data learner 1310 and the data identifier 1320 may be connected to each other by wire or wirelessly, so that information about the model established by the data learner 1310 may be provided to the data identifier 1320, and data input to the data identifier 1320 may be provided to the data learner 1310 as additional training data. At least one of the data learner 1310 and the data identifier 1320 may be embodied as a software module. When one of the data learner 1310 and the data identifier 1320 may be embodied as a software module (or a program module including instructions), the software module may be stored in a non-transitory computer readable recording medium. In this case, the at least one software module may be provided by an Operating System (OS) or by some application. Alternatively, a part of at least one software module may be provided by the OS and another part may be provided by an application.

The data identifier 1320 may be trained based on the training data using a data recognition model for determining a situation. In this case, the data recognition model may be a pre-constructed model. For example, the data recognition model may be a model that is previously constructed by receiving basic training data (e.g., sample images, etc.). The data recognition model may be constructed in advance by considering an application field of the recognition model, a learning purpose or a computer performance of the device, and the like. The data recognition model may be, for example, a neural network-based model. For example, a model such as a Deep Neural Network (DNN), a Recurrent Neural Network (RNN), or a Bidirectional Recurrent Deep Neural Network (BRDNN) may be used as the data recognition model, but the embodiment is not limited thereto.
